Blood Pressure Categories
The following table is based on guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA). Blood pressure categories are defined by the higher of the two numbers (systolic or diastolic).
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | < 120 | and < 80 |
| Elevated | 120 – 129 | and < 80 |
| High Blood Pressure (Stage 1) | 130 – 139 | or 80 – 89 |
| High Blood Pressure (Stage 2) | ≥ 140 | or ≥ 90 |
| Hypertensive Crisis | > 180 | and/or > 120 |
Hypertension & Lifestyle Tips
Hypertension (high blood pressure) is often called the "silent killer" because it usually has no symptoms but significantly increases the risk of heart disease, stroke, and kidney damage. The good news is that lifestyle modifications can prevent or manage it effectively.
Reduce Sodium
Limit processed foods and aim for less than 2,300 mg of sodium per day (ideally 1,500 mg). Check nutrition labels and cook at home when possible.
Stay Active
Aim for at least 150 minutes of moderate aerobic activity per week. Brisk walking, cycling, and swimming are excellent choices for heart health.
Maintain Healthy Weight
Losing even 5–10% of body weight can significantly lower blood pressure if you are overweight. Combine diet and exercise for sustainable results.
Limit Alcohol & Quit Smoking
Excessive alcohol raises blood pressure. Limit to one drink per day for women and two for men. Quitting smoking improves artery health immediately.
